What Causes Eye Squint and Strabismus in Cats?

Crossed eyes in cats, in its simplest definition, can be described as the inability of the eyes to focus on the same point. This eye deviation, medically known as strabismus, is often referred to as squint. It is a common condition in cats. A kitten being born with strabismus usually does not affect its quality of life later on and is not considered a problem. However, a cat owner who suddenly notices their cat is cross-eyed will understandably be worried. Such a situation may indicate a problem in the muscles that move the eye, the part of the brain that coordinates the movement of the eye muscles, and the nerves. You can learn more about strabismus in cats, and find information about eye diseases that can cause strabismus and their treatment in the rest of our article.

Eye Strabismus and Anatomical Structure in Cats

Cats have small muscles that control the movement of the eyeball to the right, left, and sideways. If an eye muscle is too long or too short, or if the nerves responsible for the function of the eye muscles are damaged, the eye cannot move normally. This causes strabismus in cats, making them appear crossed. Strabismus can affect one or both eyes.

Strabismus can affect a cat's ability to focus and impair its depth perception. Some cats may have difficulty accurately perceiving distances when jumping or seeing food in their bowls properly. Strabismus alone does not cause blindness; cats born with strabismus usually adapt well and live a normal life. However, a cat suddenly developing strabismus in adulthood may be a sign of another underlying problem that needs to be treated. Genetic Factors and Eye Misalignment In cats, eye misalignment can be caused by genetic inheritance. Strabismus is common in some cat breeds, including those of Asian origin such as Siamese cats. Many Siamese cats are born with strabismus. In fact, for many years, strabismus was considered a breed characteristic of Siamese cats. Inward strabismus, where the muscle at the inner corner of the eye is too short and pulls the eyeball towards the nose, causing a crossed appearance, is the most common type of strabismus in breeds of Asian origin such as Siamese cats. Outward strabismus occurs when the muscle at the outer part of the eye is too short and pulls the eye to the side.

Inward strabismus, where the muscle at the inner corner of the eye is too short, pulling the eyeball towards the nose and causing a crossed appearance, is the most common type of strabismus in Asian breeds such as Siamese cats. Outward strabismus, on the other hand, occurs when the muscle at the outer part of the eye is too short, pulling the eye to the side.

Health Problems and Treatment Options Related to Strabismus (Eye Movement)

Unlike congenital strabismus, sudden onset strabismus in cats may indicate a problem. If you notice that one or both of your cat's eyes are suddenly in an abnormal position, that the eyes are moving uncoordinatedly, or if they show any other signs of illness, you should report this to your veterinarian. Symptoms that may be associated with strabismus and may indicate a more serious underlying problem include:

• Rapid eye movement, known as nystagmus, occurring up and down, side to side, or in a circular motion
• Pupils of different sizes or not constricting when exposed to light
• Drooping eyelid
• Bulging eye
• Head tilted to one side
• Drawing circles or falling to one side
• Seizures
• Weakness and/or fatigue being
• Yemek yememe
• Vomiting
• Fever

If a cat develops non-genetic strabismus, both the strabismus and the underlying problem should be treated. Your veterinarian will perform a complete physical examination and also check the condition of the eyes. The eye examination process includes various tests, including light tests, eye pressure tests, and eye staining. Your veterinarian may also test your cat's cranial nerve reflexes, leg reflexes, and balance. A neurological examination may also be performed. Other tests may be necessary if deemed appropriate.

Strabismus can be corrected surgically. Under general anesthesia, the affected eye muscles are manipulated to realign the eyes. Surgical intervention may be performed to drain abscesses caused by various wounds if strabismus is caused by these wounds. If strabismus is caused by a tumor, surgery and radiation therapy may be used to treat the cancer. In some cases, complete removal of the eye may be necessary. In the presence of abscesses, meningitis, or inner ear infections affecting the vestibular system, medications such as antibiotics may be needed to help treat strabismus. Physical therapy may also be necessary for cats before or after surgery. It is important to fully follow the veterinarian's instructions during treatment and to administer medications to cats as prescribed. Why Do Hamsters Tremble?
